bluetoothd high cpu usage

Updated / Installed 12.2 - used the full installer over the previous 12.1). Again the problem returned after a few days. (Mid-2015 MacBook Pro 15") Seems happen after waking from sleep when raising lid) Only bluetooth accessory used occasionally with the MacBook are AirPods. Tried deleting all paired bluetooth devices and deleting 'com.apple.Bluetooth.plist' with a restart - no change. Issue returned next day. I read that "With Monterey, Apple has completely rewritten the bluetooth stack" so this is likely a bug with certain bluetooth cards used in these notebooks.

Hey folks, I too can confirm that the solution I shared doesn't work. The issue returned a few days later :-(

For what it's worth, simply opening Bluetooth Preferences causes the bluetoothd process to stop freaking out (on my end).

I'm hopeful that Apple fixes this in the next OSX update because Bluetooth is a core function and no one enjoys loud fans, hot laps, and dead batteries.

Just stop the process from the activity monitor

I found a quick way if you don't need bluetooth right now. just double click on the process and then end the process. then it's quiet.

I have exactly the same issue, on a 2015 MacBook Pro (15") running macOS 12.1 Monterey. The fans go crazy, and bluetoothd goes wild and takes up all the CPU time.

This issue has happened multiple times. It did NOT happen on macOS 12.0.1. I have rebooted multiple times since installing macOS 12.1. The advanced Bluetooth reset options previously available by option-shift-clicking the Bluetooth menu appear to have been removed in Monterey.

I have the same issue on a Mid-2015 MBP 15", MacOS 12.1

Opening the lid sends the process >2xx% CPU. The possible BT connections are Airdrop being active, and an iPhone and Watch in the area. Switching off BT in the Menu Bar resolves the immediate issue.

MacBook Pro Mid 2015. Problem persists even after update to Monterey 12.2.1. High CPU usage appears inconsistently and only once per day, directly after opening the lid in the morning. Manually quitting the process bluetoothd in Activity Monitor resolves the problem at least until the next morning. Fortunately and easy fix but remains a huge annoyance.

That is interesting, shott85.

In fact, this seems to have a very logical connection, though the details are yet to be determined.

It may help to provide this information directly to Apple, via Apple’s Feedback: Product Feedback - Apple.

The next MacOS Monterey 12.3 update went to the RC release candidate stage on Tuesday 3/8. I've heard this update appears to resolve the bluetoothd process bug. History suggests this update could be released any day now - probably early next week.

Have the same config and have the same issues since the latest upgrade. Since bt off, problem solved. But not sure if that is normal.

Didnt have such an issue in the previous 6 years.

Please report the bug to Apple officially as @tree_frog has suggested above! I did report it too. The more report we submit, the more likely it gets fixed.

You don't have to turn your MacBook off to get rid of the high CPU load. It is quite sufficient to toggle the bluetooth off and back on in the menu bar.

Since the 12.4 update, I've experienced it only once.... I'm on 12.5 now and it's already okay

Same issue here, I have a Macbook Air from Early 2015 and I am running macOS Monterey 12.1. Turning the bluetooth off and on is a temporary fix that works for me.

I didn't have any issue with the latest version of macOS Big Sur.
